AKS previews are partially protected by customer support for the a best-energy basis. As a result, these features commonly designed for development fool around with. To find out more, see the pursuing the help stuff:
This article assumes on which you have a current AKS class. If you’d like an AKS team, understand the AKS quickstart utilizing the Blue CLI, having fun with Azure PowerShell, or by using the Azure portal.
Need the newest Blue CLI variation dos.0.61 or later hung and you will set up. Work at az –version to find the adaptation. If you want to setup or improve, look for Create Blue CLI.
